Accounting support

ONE PLUS provides bookkeeping for JDG sole traders and limited companies in Poland. We review source documents, calculate taxes and contributions, prepare filings and monitor the agreed deadlines. Before onboarding, we confirm the business form, tax method, VAT status, document volume and payroll needs.

Monthly support can cover a revenue ledger or KPiR, full company accounts, PIT, CIT, VAT, ZUS, payroll and responses to official correspondence within the contracted scope. Documents can be exchanged remotely, so the service is available to clients throughout Poland.

The business owner receives a clear schedule for documents and payments, with figures that match contracts, bank statements and actual activity. This supports routine compliance and provides a coherent financial record when income must be shown to a bank, leasing provider or residence authority.

What regular bookkeeping in Poland should cover

After registration, a business must maintain source documents, meet ZUS and tax deadlines, and keep its records consistent. Language or filing errors may surface months later as a surcharge, a fine, a bank query or questions during a temporary residence card (TRC) case.

ONE PLUS has worked with foreigners and businesses in Poland since 2018. Our experience in immigration and administrative procedures helps us keep accounting consistent with the client’s contracts, taxes, social contributions and other official records. Based in Wrocław, we support clients across Poland.

This page is general guidance. Final decisions on taxes and contributions belong to the tax office and ZUS.

What the service covers

Day-to-day books

We collect invoices, contracts, bank statements and costs, check consistency, and keep records under the tax model you use. For sole traders (JDG) that usually means revenue records or a revenue-and-expense ledger. For Sp. z o.o. companies it means full accounting and year-end reporting.

Tax returns

Depending on your structure we prepare PIT, VAT, VAT UE filings where needed, and CIT for companies. Annual returns and corrections are handled when the facts require them. Official references: podatki.gov.pl. If you also receive employment income, PIT-11 / PIT-37 support may be relevant.

ZUS and payroll

Registrations, contribution calculations, employment documents, hires and terminations. Common errors include: wrong insurance codes, missed deadlines, or confusion between employment contracts and B2B invoices.

External packs

Statements for banks, leasing, equipment rental, income confirmation, and materials that support a business plan for TRC. Offices look for coherence. CEIDG/KRS data, tax filings and contracts should describe the same business.

Who it fits

Freelancers and B2B specialists

Multiple clients, mixed currencies, occasional cross-border VAT questions. Monthly discipline matters more than sophisticated “optimisation”.

Trade and e-commerce

Purchases, logistics, returns and supplier docs. Without clean source documents, the monthly result cannot be calculated reliably.

Companies with foreign shareholders

Higher formal burden, CIT, board payments, dividend questions, and often a parallel residence strategy for founders.

Founders preparing a residence case

Accounting creates a traceable history. Starting early is cheaper than reconstructing six months of incomplete records before an appointment.

JDG vs company: different accounting pressure

A JDG is lighter at the start, but your tax form (scale, flat rate, or lump-sum ryczałt) changes how income looks. An Sp. z o.o. needs fuller books and stronger document hygiene. There is no universal “cheapest” path. Choice depends on risk, partners and growth plans.

Without PESEL, many e-government and banking flows are harder. Business address and registration of residence (zameldowanie) also affect official mail. We check that registry, bank and accounting data match.

How cooperation works

1. Short briefing: entity type, turnover, VAT, staff.
2. Contract with a clear scope and fee.
3. Document channel setup.
4. Monthly calculations and filings.
5. Payment reminders with plain-language explanations.
6. Optional packs for banks or immigration procedures.

Useful public portals: biznes.gov.pl. We turn the applicable obligations into a practical document and payment schedule.

Common bookkeeping mistakes

Mixing personal and business spending

Makes profit hard to prove and weakens banking or TRC evidence.

Late VAT or ZUS registration

Consequences arrive late and usually cost more than an early consult.

Conflicting addresses and names across systems

Small mismatches trigger letters and delivery problems.

Invoices without contracts

Harder to defend costs or show stable revenue when asked.

Practical notes for 2026

Digital filing is convenient, but less forgiving. Missed returns, incomplete attachments or silent gaps in source documents create follow-up requests. In practice, missing or late source documents cause more avoidable work than the calculations themselves.

If you are still registering a business, a sensible order is: confirm your right to operate, arrange PESEL if needed, register the activity, then connect accounting from month one. Catch-up bookkeeping is possible, but slower.

ONE PLUS works under contract, from a Wrocław office, with transparent scope. We do not replace public authorities and we do not promise “zero audits”. We reduce avoidable errors and keep deadlines under control.

Accounting price list

Below are current ONE PLUS net rates. Gross depends on VAT. Final scope and fee are confirmed in the contract after a short brief: business form, document volume and hiring.

Bookkeeping for JDG

For JDG (sole proprietorship) we keep revenue records / KPiR, taxes and ZUS. Starting rate:

From 300 zł net per month, depending on document volume, VAT and ZUS. After the brief we confirm the exact rate.

Commercial books (księgi handlowe) for Sp. z o.o.

Księgi handlowe means full company accounting: ledgers, returns and reporting. It applies to Sp. z o.o. and other forms that require full books. Rates by monthly document volume:

Higher volumes or payroll are quoted individually. A package with a business account and company setup is agreed separately.
